1. Basic parameters:
Frame current level: "1106" in "3WL1106" may represent the frame current level of the circuit breaker, which is a specific specification identification for this series of circuit breakers. Different combinations of numbers correspond to different current carrying capacity ranges.
Pole number: It is not explicitly mentioned here, but generally speaking, this type of frame circuit breaker has 3 or 4 poles and can be applied to different circuit systems.
2. Performance characteristics:
High current breaking capability: It can quickly and reliably cut off the circuit in case of overload, short circuit or other faults, protecting the safety of electrical equipment and lines. Its breaking capacity is usually high and can meet the requirements of large-scale industrial and commercial power systems.
Good thermal stability: During normal operation, it can withstand a certain current load without excessive heating, ensuring the long-term stable operation of the circuit breaker. Even in high ambient temperatures, it can maintain good performance.
Long mechanical lifespan: The mechanical structure design of the circuit breaker is reasonable, and the operating mechanism is flexible and reliable. After multiple opening and closing operations, it can still maintain good performance and has a long mechanical lifespan. This is particularly important for circuit systems that require frequent operation.
3. Attachments and functions:
4GA4: This section may represent some specific accessories or functional configurations of the circuit breaker. For example, accessories such as auxiliary contacts and alarm contacts may be included to monitor and provide signal feedback on the status of the circuit breaker; It may also involve some special protection functions, such as leakage protection, overvoltage protection, etc.
Possible meaning of "Z": The "Z" in the model may be an identifier added by the manufacturer to distinguish specific versions, feature extensions, or other special configurations of the product. The specific meaning needs to refer to Siemens' relevant product documentation or consult the manufacturer.
4. Application scenarios: Suitable for use as incoming circuit breakers, bus tie circuit breakers, or feeder circuit breakers in power distribution systems of various large industrial, commercial, and civil buildings. It can be used to protect electrical equipment such as motors, capacitors, generators, transformers, busbars, and cables, ensuring the safe and stable operation of the power system.
